Probabilistic Building Inspection and Life Assessment - a computer program for reliability based system assessment

Abstract: The collaborative research centre (CRC) 477 explores innovative methods for structural health monitoring. In project field A1, methods and strategies, the modular knowledge-based computer program PROBILAS (Probabilistic Building Inspection and Life ASsessment) is developed. Its main focus lies on the optimization of structural health monitoring measures. One opportunity to optimize the monitoring process is to concentrate the monitoring measures on a few critical weak points of a structure. These critical weak points are identified by using methods of the system and reliability theory. Additionally these methods provide the opportunity to evaluate and to assess the probability of failure of a system. This paper concentrates on the implementation of the described methods into PROBILAS. Especially the database model, its integration into the program modules and the calculation procedure used for reliability analysis are discussed further.
